Unity’s physics system lets you handle 2D physics to make use of optimizations available with 2D.
Note: You can also use the separate Physics Core 2D API to use 2D physics. The API doesn’t interact with or affect built-in Unity 2D physics components such as RigidBody 2D and Collider 2D. For more information, refer to Introduction to the Physics Core 2D API.
You can use the following physics 2D components with Unity:

|---|---|
| Rigidbody 2D | Learn how Rigidbody 2D works. |
| Collider 2D | Understand the types of Collider 2D components available to use with Rigidbody 2D. |
| Effectors 2D | Approaches and techniques to working with the forces of physics when GameObject colliders are in contact. |
| 2D joints | Understand the types of 2D Joints available to use with 2D GameObjects. |
| Physics 2D Profiler | Approaches to analyzing the performance of 2D physics in your application. |
| Constant Force 2D reference | Explore the properties that control constant forces applied to a Rigidbody 2D. |
| Physics Material 2D reference | Explore the properties that control the friction and bounce between colliding 2D physics objects. |
